This is the problem that I encountered after upgrading my a7000 to version 6.0 Marshmallow.
1. Please fix the issue, because my video was too dark every time I will make video call to my family. I reset everything on my camera but still no changes.
2. If no chance to fix these issue, how to return the system of my a7000 to version 5.0? and what are those steps? Because the first time I encounter this problem, I made a factory reset just to think if possible to return into a version 5.0.
3. Please reply.

The Lenovo A7000, I bought it last year June month, I am using this phone as a business Tool, its performance is cool, last month I suddenly come across with problem in touch screen ( Only one corner) that not make any obstructions in my regular activities with phone. I took this phone to Authorised service provider & who use to inform minimum 10 days required to replace touch screen. But I got call within 4 days stating that phone is ready. Overall a strongly recommend this phone because it has many features like expensive phones in Samsung. I am completely satisfied with my Lenovo A7000 phone. And talking about service provider, really you may not have any other phone company, such communication which is providing Lenovo between customer and service center about phone status and all is really sounds cool.

I updated successfully to Android 6.0 marshmallow. Now everything is superb. No hanging and battery drain issue. Working very smoothly. Factory reset your. Mobile then start update. Or start update on morning time because lenovo server is full that's why you are unable to update. After update again perfom a full factory reset. Then no problem. Better than previous Android 5.0

Hii Friends,
Yesterday i updated my device to Android 6.0.After the update volume level reduced upto 50%.Dolby Atmos Equalizer was not able to modify.Because of this reason i degraded my lenovo a7000 from Android 6.0(MARSHMALLOW) to Android 5.0(LOLLIPOP).Lenovo Marshmallow update consist of many bugs.so it is better to avoid this update.Android Lollipop is FINE!!
